Infineon Technologies MOTIX™ MCU

The MOTIX™ MCU TLE988x and TLE989x devices utilize a B4 or B6 bridge N-channel MOSFET driver, respectively, an Arm^® Cortex^®-M microcontroller, and a CAN (FD) controller and transceiver (2 Mbps). Customers benefit not only from fast and robust communication but also from the highest computing performance thanks to the high system frequency (60 MHz) and its dual flash supporting read-while-write operation. Most of the MOTIX™ MCU TLE988x and TLE989x products are ISO 26262 (ASIL B) compliant and some variants have built-in cybersecurity. All of these features are offered in a 7 mm x 7 mm QFP package with a market-leading footprint.
